This article looks at the role that vacuum casting plays in the rapid prototyping and rapid manufacturing process. The accuracy to which components can be reproduced, by looking at the controllable factors in the casting ...

South African manufacturing companies today need to be more sophisticated technologically to compete for global markets. The latest trend in automation and manufacturing emerges in the form of reconfigurable systems. The ...

Optimizing the output power of any PV module involves a number of factors, including the orientation angle. However, many PV modules are not installed at the suggested orientation angle of 0° N in South Africa, thereby ...

Optimizing the output power of any PV module
involves a number of factors, including the tilt angle, orientation
angle and environmental conditions. However, many PV modules
are not installed at the suggested orientation ...

Optimizing the output power of any PV module involves a number of factors, including the setting of the tilt angle. The purpose of this paper is to present empirical evidence validating the optimum tilt angle for PV module ...

Authors who support the notion that the responsibility of businesses goes beyond profit-making to include social and environmental objectives have largely found a positive relationship between business social responsibility ...

The incidence of epilepsy is high in sub-Saharan Africa and resource poor countries (RPCs). There are few neurologists and paediatric neurologists to manage people with epilepsy (PWE). Health care is often limited, ...

In this research, a nylon/aluminium composite (Alumide®) material was investigated for its suitability to produce moulds for injection moulding through an additive manufacturing process. Literature shows that Alumide® has ...

Direct metal laser sintering (DMLS) is a relatively new technology that is developing rapidly. Since DMLS material is created by melting/solidifying tracks and layers from powder, even building geometry can influence the ...

One aspect of project management that requires attention is value creation and inherent challenges in the construction industry. The purpose of the research is to ascertain the factors affecting value creation and to ...

The long-chain fatty acids of 52 Kluyveromyces strains were extracted by saponification and analyzed as methyl esters by gas chromatography. The similarities between the strains were calculated on the basis of their fatty ...

It has been observed that when samples from one particular layer of one particular test pit are analysed by different laboratories the results may vary over an alarmingly large range. Jakobsz and Day (2007) suggested that ...

Partial shading of a PV module has received much attention over the past few years, as it results in uneven cell power generation, compromising a PV system performance. Full uniform shading of a PV module has not received ...

This study discusses two types of verbal alternation in Sesothothat have the same syntactic structure, but differ in their semantic representations and in their lexical syntax structures. The first scenario: ‘Ntate o ...

Optimizing the output power of any PV module
requires a number of factors to be considered, including the tilt
angle, orientation angle, environmental conditions and the
energy management system. This system often ...

The Water Administration System (WAS) is designed to be a management tool for irrigation schemes and water control offices that want to manage their water accounts and supply water to clients through canal networks, pipelines ...

The calming of traffic has three main aims, namely:
1. To enforce an appropriate speed for a specific situation.
2. Furthermore there is a link between manoeuvrability and accessibility. The more
manoeuvrability there ...

One of the most important decisions an entrepreneur can make is to determine the physical location of the enterprise. Each enterprise has its own ideal place. The place of establishment must contribute to the optimal ...
